3.3 Ohm (3.3E) 1/4W 5% Through Hole Resistor

The 3.3 Ohm (3.3E) 1/4W 5% Through Hole Resistor is a versatile and reliable component that offers a slightly higher resistance than the 3-ohm version, making it ideal for applications requiring moderate current limiting or voltage regulation. This resistor is suitable for low-power electronic circuits and is commonly used in both professional designs and hobbyist projects. Here’s a breakdown of its key features:

Resistance Value (3.3 Ohms):

This resistor has a resistance of 3.3 ohms, providing a moderate level of current resistance. It's commonly used in circuits where you need to control current flow without allowing too much current to pass through, such as LED circuits, power supplies, and signal processing applications.

Power Rating (1/4W or 0.25W):

With a 1/4 watt (0.25W) power rating, this resistor is designed to dissipate up to 0.25 watts of electrical energy as heat. It’s ideal for low-power applications, ensuring that the resistor will not overheat during typical operation, thereby maintaining safe and reliable circuit performance.

Tolerance (5%):

The 5% tolerance means that the actual resistance can vary by ±5% from its nominal value of 3.3 ohms. This tolerance is typical for general-purpose resistors, offering a reasonable degree of variation for most standard applications where ultra-precise resistance is not necessary, but consistency is important.

Through-Hole Mounting:

This resistor features a through-hole design, meaning it has leads that are inserted through holes in a printed circuit board (PCB) and are soldered on the opposite side. This mounting style is durable, easy to handle, and commonly used in both prototyping and finished products. The through-hole design also makes it simple to replace or repair the component if necessary.

Material and Durability:

Typically made from carbon film or metal oxide, the resistor is durable and cost-effective, built to handle typical operating conditions in low-power circuits. These materials ensure the resistor's reliability and longevity, even when exposed to standard temperature and voltage variations.

Applications:

• Current Limiting: The 3.3-ohm resistor is widely used for current-limiting purposes, especially in circuits such as LED drivers, where it controls the amount of current flowing through LEDs to protect them from overcurrent damage.

• Voltage Divider: It can be used as part of a voltage divider network, particularly when precise voltage levels need to be created in low-voltage circuits or sensors.

• Signal Filtering: The resistor is also suitable for filtering applications when paired with capacitors or inductors. It helps create low-pass filters, high-pass filters, or band-pass filters for audio or RF applications.

• Power Regulation: The 3.3-ohm resistor can be used in power supply circuits to regulate current or manage voltage drops across different components, ensuring stable performance in sensitive devices.

Ease of Handling and Repair:

Thanks to its through-hole mounting, this resistor is very easy to handle, solder, and replace if needed. This is especially beneficial in prototyping and repair work, as it allows for quick modifications to the circuit or easy replacement of faulty components.

In Summary:

The 3.3 Ohm (3.3E) 1/4W 5% Through Hole Resistor is a highly reliable and affordable component suitable for a variety of low-power applications. Its moderate resistance value of 3.3 ohms, coupled with its 1/4W power rating, makes it ideal for use in current-limiting circuits, voltage division, signal filtering, and power regulation. Whether you're working on DIY electronics, prototyping, or professional designs, this resistor ensures consistent and stable operation in your circuits.

This resistor is a great middle-ground option for circuits that need slightly more resistance than lower values like 3-ohm or 2.7-ohm, but still within a safe operating range for low-power devices. If you have specific use cases or need more details, feel free to ask!
